The following example illustrates how to retrieve an IWMSActiveStream object.
using Microsoft.WindowsMediaServices.Interop;
using System.Runtime.InteropServices;
// Declare variables.
WMSServer Server;
IWMSActiveMedia ActiveMedia;
IWMSActiveStreams ActiveStreams;
IWMSActiveStream ActiveStream;
IWMSPlayers Players;
IWMSPlayer Player;
IWMSPlaylist Playlist;
try {
// Create a new WMSServer object.
Server = new WMSServerClass();
// Retrieve an IWMSPlayers object.
Players = Server.Players;
// If players are connected, retrieve first IWMSPlayer object
// in the IWMSPlayers collection.
if (Server.Players.Count > 0)
{
Player = Server.Players[0];
// Retrieve the IWMSPlaylist object for the player.
// NOTE: A valid playlist file is not always returned.
// This may be the case, for example, if the user requested
// a specific content file or if a broadcast publishing point
// is being used.
Playlist = Player.RequestedPlaylist;
if (Playlist != null)
{
// Retrieve the IWMSActiveMedia object.
ActiveMedia = Playlist.CurrentMediaInformation;
// Retrieve the IWMSActiveStreams object.
ActiveStreams = ActiveMedia.Streams;
// Retrieve information about each active stream.
for (int i = 0; i < ActiveStreams.Count; i++)
{
// Retrieve the IWMSActiveStream object.
ActiveStream = ActiveStreams[i];
}
}
